$$P_1$$ $$V_1$$ = $$P_2$$ $$V_2$$

Question 4

Which lymphoid organ is the site of T lymphocyte maturation?

Question 5

A researcher is studying the movement of gases between alveoli and capillaries. Which law best explains the diffusion of oxygen and carbon dioxide across the respiratory membrane?

Accepted Answer

Henry's Law

Question 6

Which of the following is a major component of MALT (Mucosa-Associated Lymphoid Tissue)?

Accepted Answer

Peyer's patches

Question 7

A patient with a genetic defect in plasma cell production would most likely have difficulty with which aspect of immunity?

Accepted Answer

Production of antibodies

Question 8

Which of the following best describes the role of surface barriers in the immune system?

Accepted Answer

They act as the first line of defense by preventing entry of pathogens.

Question 9

During an allergic reaction, which antibody class is primarily involved?

Accepted Answer

IgE

Question 10

Which of the following best explains why oxygen is efficiently loaded onto hemoglobin in the lungs?

Accepted Answer

High partial pressure of oxygen and low temperature in the alveoli.

Question 11

Which structure in the upper respiratory system is primarily responsible for humidifying and filtering inhaled air?

Accepted Answer

Nasal cavity

Question 12

A patient is exposed to a novel virus. Which immune cells are most likely to present viral antigens to T cells to initiate an adaptive immune response?

Accepted Answer

Antigen-presenting cells (APCs)

Question 13

Which of the following equations represents the calculation of partial pressure of a gas in a mixture according to Dalton's Law?

Accepted Answer

$$P_{total} = P_1$ + P_2$ + P_3$ + \ldots$$

Question 14

Which of the following best describes the difference between diffuse and follicular lymphoid tissue?

Accepted Answer

Follicular lymphoid tissue contains germinal centers for B cell proliferation, while diffuse tissue does not.

Question 15

A person at high altitude experiences increased ventilation. Which physiological change is most responsible for this response?

Accepted Answer

Decreased arterial $$P_{O_2$}$$

Question 16

Which of the following is NOT a function of the spleen?

Accepted Answer

Maturing T lymphocytes

Question 17

Which of the following best describes the process of phagocytosis in innate immunity?

Accepted Answer

Engulfment and digestion of pathogens by specialized cells

Question 18

A patient with chronic bronchitis is likely to experience which of the following changes in respiratory function?

Accepted Answer

Decreased tidal volume and increased airway resistance

Question 19

Which of the following best explains the effect of fever in the innate immune response?

Accepted Answer

Fever increases the metabolic rate and impairs pathogen replication.

Question 20

Which of the following is a correct statement about the structure and function of the respiratory membrane?

Accepted Answer

It is composed of alveolar and capillary walls with a fused basement membrane, facilitating gas exchange.
